I was a very flat 32a, was offered 260, 300, and 340cc. I was a bit scared of looking too big so wanted 300. On the day of my surgery, my surgeon said he was going with 340! Thank god he did because i still feel quite small now under clothes. I measure a 32dd but dont look anywhere near as big as my naturally 32dd sis in law. I look about a c which is exactly what i wanted and i love them, just feel small sometimes. Implants always measure larger than natural boobies (dont ask me why lol) x
